Product features

Bell jar with ground-in glass stopper is made of glass and has extremely high transparency, allows users to clearly observe the internal conditions.Whether you are conducting chemical reactions, physical experiments or observing biological phenomena, it can provide intuitive visual effects. It is convenient for users to monitor the experimental process in real time, discover problems in time and adjust experimental parameters.

Glass generally has good chemical stability and is resistant to attack by most chemicals. For some highly corrosive substances, glass round bell jars can provide reliable protection.The circular design has uniform force distribution and can withstand a certain amount of pressure without being easily deformed. The equipped glass stopper can be tightly combined with the bell jar to form a good sealing effect. This is critical for experiments that need to be performed under specific gas environments or vacuum conditions. Effective sealing prevents gas leakage or the entry of outside air, ensures the stability and repeatability of experimental conditions. At the same time, it can also avoid the volatilization and contamination of experimental substances and ensure the safety of the experiment. Stopper bells are usually designed with ease of operation in mind. Its shape and size are easy to hold and place, and the insertion and removal of the glass stopper is also smooth, makes it convenient for experimenters to operate.
